One question.  Does the 1.25 inch gap apply to any size ring, or should it be bigger with a bigger size?   It seems like a 20" DC ring might take a larger gap than a 14 or 16".

Way to go David.  Your baffle in the DC is what I was speculating about in my post about going bigger.  When I get some time I will 'borrow' some of your hard work to make mine.  It will be on a 3HP four bag DC, and I will do it with no filters at all, just a lid over the top of the DC ring for the center outlet....
with a 6" from each side to a wye with one 8" outlet to the outside.  With the DC being as efficient as you demonstrate, I should not have much other than fine dust going out, which is where I want it.

I am trying to figure out the best way to hook up the baffle idea to my 3 HP Powermatic DC.  It has an 8" inlet and a double bag setup.  The mounting hoop where the bags attach has a downward slanting flange about 2" wide which helps keep the dust headed down into the clear plastic bags, and not up to the fabric bags.

My thought is to make a baffle a few inches below this flange and put a plywood top on the hoop instead of the fabric bags.  Each one would have a 6" pipe coming out of the center and out the side of the shop.....no filter bags (California).  If it saves 90% or so, I can vent the really fine stuff outside. 

The Wynn filter site shows a setup somewhat like this, but the baffle would make it even better.

Any ideas??

One more question....Why does one bag on my dual bag setup have about 5 times as much dust in it than the other?  One side has about 3" and the other has about 15" full.
